(Cl. 17g-34) 31 Claims. 1

This invention relates to telegraphic printing and message postingapparatus and particularly to the recording of stocs quotations and theprojection of images of the quotations for display.

This application is a division of application Serial No. 273,672, filedMay l5, i939, which eventuated into U. S. Patent No. 2,284,581, datedJune 2, i942.

An object of the invention is to reco-rd on a plurality ci tapes in aprinting telegraph apparatus all of the quotations pertaining to aselected gro-up of stocks, each of the tapes being assigned to receiveall of the quotations with reference to one of the stocks of the group,and to project on a screen current quotations from portions of a groupof tapes.

Another object of the invention is to advance each tape across the heldof the projecting apparatus only as an incident to the printing ofquotations upon that tape so that the viewing screen will therebypresent no blank tape in the projection field but instead at all timesthere will be displayed images of as many quotations on each tape in thefield of its projecting apparatus as the area of that field willaccommodate.

The invention features printing telegraph apparatus having a pluralityof tapes movable in parallel paths and a corresponding plurality of typewheels carried a common shaft for cooperation with said tapesindividually. Quotations for stocks not included in the group to berecorded are discarded and have no eect upon any of the printingmechanisms.

The invention also features the division of the horizontally movabletapes in a printer into separated groups, each group having its ownsource of illumination and optical system, and having images projectedtherefrom upon its own viewing screen or upon an assigned portion of alarge screen independently of the projection of images from other groupsof tapes, the several groups of tapes being served by individual typewheels carried by a single type wheel shaft.

In the present embodiment of the invention the type wheels are carriedby a single continuously rotatable shaft which extends through and iscontrolled by a code disc selector mechanism. This mechanism iscontrolled by a single magnet selector which also controls the settingof code bers. The code bars in turn control the setting of secondary orstorage code bars arranged in sets for storing selective conditionsidentified with the characteristic letters of the stock designations.The storage bars control the selection of printing elements, there beingone for each of the tapes, and when the sets of storage bars arepositioned for a stock designation outside the group to which theprinter is adjusted to respond,

no printing interponent is selected.

rIhe code disc selector device does not arrest the type wheel but merelytrips off a printing mechanism which strikes the selected tape againstthe rotating type wheel, the selected character being printed while thetype wheel is lrotating at normal velocity. During the reception andprinting of the stock price, the figure shift mechanism disables thestorage code bar setting mechanism so that the signals for the priceselection cannot interfere with the settings of those bars which haveresulted in the selection of a printing interponent.

Tape feeding and ink ribbon feeding operations are performed as anincident to the printing operation. This embodiment of the inventionfeatures an arrangement for advancing blank tape past the printingposition a suicient distance to bring the last printed quotation intoposition for observation or projection, and for subsequently drawingback toward the printing position the projected portion of the tapewhich had previously been advanced. Accordingly, when a next quotationis to be printed upon a tape which has been moved out for viewing thetape is retracted so as to print the new quotation closely adjacent tothe one previously printed in order that as many quotations as possiblemay be contained in the length of tape that is within the field ofobservation or of the projecting apparatus.

In accordance with one embodiment a projecting system is employed whichfeatures compactness as one of its primary considerations and involvesthe use of a plane reflector for turning a beam of light through degreeswhereby the optical system and the printer may be contained in a housingrequiring a minimum of space from front to back.

A complete understanding of the invention may be obtained from thefollowing detailed description, reference being had to the accompanyingdrawings wherein:

Fig. 14 is a view of a fragment of a tape upon which characters havebeen printed by means of the'type wheel shown in Fig. 13, the tape beingviewed from the front'.

Referring now to the drawings, a multiple tape stock quotation printeris shown in Figs. 1 to 12, inclusive. This printer is adapted to theprojection of enlarged images of the printed tapes upon screens, asshown in Figs. 11 to i4, inclusive. Referring to Figs. 1, 2, and 3, thereference numeral 40| designates a motor, the rotor shaft 462 of whichcarries a pinion 403. Pinion 463 has direct driving engagement with agear 434 secured to type wheel shaft 466 and with a' gear 401 secured toa combined selector and printing shaft 408. Shafts 466 and 468 arerotatably supported by stationary frame portions of the printer. Gear451 has secured thereto a gear 469 with which meshes a gear 4H carriedby a Vtransfer shaft 4|2 rotatably supported in brackyets 4|3.

The arrangement of shafts and gears is similar to that disclosed in U.S. Patent No. 2,247,408, issued July 1, 1941, to Albert H. Reiber.

Shaft 468 has sleeved thereon at its upper end `a selector cam sleeve4|6 to which rotation is imparted from shaft 468 by means of cooperatingdriving and driven discs at the end of sleeve 4|6, felt, or otherresilient discs being interposed between the driving and driven discs.Selector cam sleeve 4|6, in cooperation with selector magnet 4|1,controls the setting of sword levers in a sword and T-lever selectormechanism indicated generally by the reference numeral 4|8. Selector camsleeve 4|6 has a plurality of cam projections 4|9 (Fig. 1) whichindividuallyvand successively bring sword levers 42| (Fig. 4) intocooperation with a selector lever 422, the selective positions of whichare controlled by Van arma-l ture lever 423 which carries an armature424 for the selector magnet 4I1. The single magnet sword and T-leverselector mechanism is well 4known in the art of printing telegraphy, andthe 'specific embodiment shown herein is disclosed.

in the hereinbefore mentioned patent of Albert H. Reiber. The swordlevers 42| are selectively positioned in extreme clockwise orcounterclockwise positions by means of said mechanism and farethereafter moved endwise to establish corresponding selective positionsof transfer levers -426'under the control of a transfer mechanism.

The transfer mechanism comprises a bail 421,

Fig. 2, at the upper end of which is secured a bracket 426 which retainsa plurality of transfer springs 429. Springs 429 are effective upon theindividual sword levers 42| when bail 421 is operated to move the swordlevers to their extreme right-hand positions, as viewed in Fig. 4. Bail421 has secured thereto an arm 43| which is provided with a lockingblade 432 which normally locks projecting ends of transfer levers 426and which is withdrawn due to clockwise rotation of arm 43| when bail421 is operated to permit the selective resetting of transfer levers426.

Transfer bail 421 carries a cam follower roller (not shown) whichengages a cam 434 secured to a cam sleeve 436, sleeved on the transfershaft 4|2. Rotation is imparted to cam sleeve 436 through a springloaded jaw clutch 431 which is normally held disengaged by a clutchthrowout lever 438. Lever 433 is carried at the lower end of a bail 433which carries at its upper end an operating arm 44| disposed in the pathof a cam projection 442 (Fig. 1) included in selector cam assembly 4|6.A tension spring 443 biases clutch throwout lever 438 into engagementwith clutch 431 and the end of operating arm 44| in the path of camprojection 442. Upon each operation of clutch tripping bail 439, cam 434is released for a single revolution and operates its follower whichthrough arms 43| and 421 unlocks transfer levers 426 and repositionsthem in accordance with a new signal combination under the control ofsword levers 42|.

Stock quotation printers are usually operated under the control of a6-unit code, one impulse of which determines Whether figures or lettersshall be printed and the remaining live of which select the particularletter or figure to be printed. 1n conformity with this practice, theprinter now being described is provided with five of the transfer levers426, each of which has disc and slot articulation with an intermediatethree-armed lever 443 (Fig. 4) of which there are ve disposed one abovethe other upon pivot 444. Each of the intermediate three-armed levers443 has one of its arms disposed in a slot in a code disc 446, of whichthere are five permutation code discs (Fig. 3) and a special blockingdisc 441 (Fig. 4) included in a code disc selector mechanism indicatedgenerally by the reference numeral 448 (Figs. 3 and 4). The third arm ofeach of the three-armed intermediate levers 443 terminates in a discportion which is disposed in a slot near the end of a code bar 449V ofwhich there are live (Figs. 1 to 4, inclusive). Pivot 444 also supportsa lever 45| which is operatively in The engagement with special blockingdisc 441. function and control of'lever 45| will be described later. y

It will be apparent from the foregoing that when transfer levers 426areset permutatively acing to that impulse of the code combination whichidentifies the code combination Aas pertaining to letters or gures. Thesixth sword lever is aligned with and controls a T-shaped lever 452which is pivoted coaXially with the transfer .levers 426. The T-shapedlever 452 has its principal arm 453 disposed between pins 454 and 456Afrom arm 455 of lever 45?.

into engagement with a ratchet wheel 462 secured at the upper end ofshaft 453. Lever 45'! is biased in clockwise direction by spring 455(Fig. 1) engaging an arm 455 of lever 457 and urging Athe arm intoengagement with a stop post |4513. Bell crank 455 is biased incounterclockwise direction by spring engaging arm 470 Vof bell crank 453and urging the arm into engagement with post i455 on the opposite sideStop post i455 is so positioned that T-shaped lever is normally retainedby the lever 45'! and bell crank 453 in a position intermediate thepositions to which it may be rocked by its associated sword lever 421.The rocking of T-shaped lever 452 to either of kits eXtreme positions iseffected by the transfer bail 421 which moves sword levers 425 endwiserightwardly, as viewed in Fig. 4, and thus momentarily rocks T-shapedlever :352 to extreme clockwise or counterclockwise position while atthe same time setting transfer levers 42S permutatively. As the transferbail returns to nor- `mal position, it ceases to exert any effect uponcombinations is such that when the combination e pertains to the lettersof a stock quotation designation, T-shaped lever 452 is rocked inclockwise direction and, in turn, rocks pawl supporting lever 45?counterclockwise to effect counterclockwise rotation of rock shaft 453one ratchet step. A holding pawl 454 is urged into engagement withratchet 452 by a spring (not shown) to hold ratchet wheel 4? in itsnormal position or in any advanced position to which it may be rotatedby pawl 459.

Shaft 453 is biased in clockwise direction, as viewed in Fig. 4, bymeans of a torsion spring 456 (Fig. 3) and is provided at its lower endwith cams 45E', 45B, and 455 and with a stop disc 4H. Stop disc 4?! isprovided with a shoulder which is engageable with a xed bracket 4'52 ofthe frame of the machine to arrest shaft '53 when ratchet wheel 4t2 isengaged by neither of the pawls 459 and to determine the rest positionthereof.

Cams 45? to 455, inclusive, are provided for controlling the setting ofthree sets of storage code bars according to permutational settings ofthe code bars As shown in Figs. l, 3, and 6, a series of endwise movablebars 453, 414 and 416 is disposed adjacent to the cams 45? to 45),inclusive. Bars 4l3, 4'1'4, and it are disposed one above the othercorresponding to the spacing of cams 45? to 455, inclusive, and each ofthe bars pivotally supports an interponent lever 4H', 418, and 4215,respectively, which levers are aligned horizontally with cams 457, 455,and 465 respectively and are urged into engagement with the cams bysprings, such as 48! (Figs. l and 6). Cams 4E? to E58, inclusive, areprovided with recesses as at 432, 459, and 453, respectively (Figs. 1and 6) which may be entered by the cam engaging ends of interponentlevers 4l? to 479, respectively, when cams 4S? to 455, respectively,have been rotated into position to present their recesses. The angulardisposition of cams 461 to 45,9, with reference to their individualnterponent levers 4?'1 to 459, respectively, is such that when shaft 453is in normal position with the shoulder of stop disc 47| engaging fixedstop 412, none ofthe recesses 482, 435, and 483 is presented to aninterponent lever. When ratchet 452 has been advanced one step incounterclocliwise direction cam 45t is rotated sufficiently to bring itsrecess 432 into alignment with the cam engaging end of its interponentlever 47?, which responds to its spring 43! and enters the recess 482,the interponent 4'1'7 thus rotating in clockwise direction, as viewed inFig. i. When ratchet 462 is rotated another step in counterclockwisedirection by pawl 459, the recess 452 in cam 467 is moved out ofregistry with the cam engaging end of interponent 4W and the recess S5in cam 4% is presented to the cam engaging end of interponent 'i.Similarly, when shaft is rotated another ratchet step incounterclockwise direc- .ion, interponent 478 is restored to its normalposition by the movement of the recess 485 in cam 458 out of registrywith the interponent, and recess in cam 455 is presented to the camengaging end of the lowermost interponent 47B.

Adjacent to the left-hand end of the bars 413, 414, and 476, as viewedin Fig. 3, is the depending arm 484 of a bail 485 pivoted at 451. Bail485 is provided with a cam follower roller 458 which engages a cam 489included on cam sleeve 435 carried by transfer shaft 4I? and driven byclutch mechanism 431. When cam 489 is rotated, bail 455 is rockedcounterelockwise, as viewed in 3, and its depending arm 484 is movedrightwardly a predetermined distance and is then restored to normalposition, which is that shown in Fig. 3, by tension spring 49. Bail arm484 clears the left-hand ends of bars 473, 474, and 4i5 as it movesrightwardly, but the left-hand end of any of the interponent levers 4T?,418, and 479, which is rocked in clockwise direction due to entrance ofits cam follower portion into a recess in its corresponding cams 457,463, or 455, moves into the path of bail arm 484, and as the arm ismoved rightwardly, rightward motion is imparted to the bar 413, 414, or425 by which such interponent is carried. The right-hand ends of bars413, 4'54, and 416 are step Cut so that they may individually engagedepending operating arms of nested bails 452, 493, and 454,respectively, pivoted upon shaft 45S.

Previous reference has been made to sets of storage code bars. There arethree such sets, the rst set being designated 513i, the second 502, andthe third 583. Storage code bars 50i, 552, and 553 are individuallysupported near their lower ends by being provided with two pins 504 and595, Fig. 3, between which extend horizontal arms of transfer bellcranks 557, there being a transfer bell crank individual to each of thestorage code bars. As the storage code bars are arranged in sets, soalso are the transfer bell cranks 557, those individual to the code bars59! being pivotally supported as at 558 in a transfer bail 559, thoseindividual to Code bars 552 being pivoted at 5H in a transfer bail 5l?and those individual to the code bars 5i3 being pivoted at 553 in atransfer bail 5i4. Bails 55d, SI2, and 554 are pivoted upon pivot rod555, and each has a depending operating arm, the arms being designated5H, 5w, and 5l9 for the bails 5tlg, 5i2, and 5l4, respectively. Adjacentto the lower ends of the bail arms 5H, 518, and 5&9, bails 452,493, and494 are provided with laterally exmal condition, a fixed stop 534.

tending projections 52|, 522 and 523, respectively, in the operativepath of which the lower ends of bail arms 511, 510, and 519 aredisposed. As viewed in Fig. 3 upon the rightward reciprocation of any ofthe bars 413, 414, and 416, its corresponding bail 492, 493, or 494 willbe rocked counterclockwise and will, in turn, impart counterclockwiserocking movement to the corresponding bail 509, 512, or 514 through itsdepending arm 511, 518, or 519, respectively.

Storage code bars 501, 502, and 503 are individually urged downwardly bymeans of tension springs 524 (Fig, 3) to seek engagement with a stoprail 526. These bars are movable under the control of transfer bellcranks 501, as will presently be described, from their lowermostpositions engaging the stop rail 526, which is one of their selectivepositions, to an upper and therefore alternative selective position, inwhich position they are held by individual latches 521 pivoted on apivot rod 520 and biased in clockwise direction, as viewed in Fig. 3, byindividual tension springs 529. The clockwise movement of latches 521when their individual bars 501, 502, and 503 have been lifted free ofthose latches is limited by a bail 531 which is also pivoted upon rod528 and which spans all of the latches 521. When any of the bars 50|,502, and 503 is lifted to its upper selective position, it rests uponits associated latch 521, which has been moved in clockwise direction byits spring 529 and which remains in that position until retracted topermit the storage code bars 501, 502, and 503 to return to normalposition.

The retraction of latches 521 is accomplished by bail 531 which has atits left-hand end, as viewed in Fig. 1, a depending arm 532 whichterminates close to the upper surface of reciprocable bar 413, Bail 531is biased clockwise by tension spring 533 (Fig. 3) to engage, in thenor- Reciprocable bar 113 has pivoted upon the upper surface thereof asat 536 a trip-off lever 531 (Figs. 1 and 3) which consists of two arms,one extending along bar 413 and terminating adjacent the lower end oflatch tripping bail arm 532 which is disposed in its path, and the otherextending transversely from bar 413 and having in its path a xed pin 538(Fig. l). A spring 1531, Fig. 6, maintains lever 531 in its extremeclockwise position resting against a stop lug integrally formed with thebar 413. Upon rightward reciprocation of bar 413, as viewed in Fig. 3,the end of the arm of trip-oif lever 531 which extends along bar 413engages latch restoring bail arm 532 and rocks the bail counterclockwiseto withdraw latches 521 from supporting engagement with any of thestorage code bars 501, 502, or 503, that may be in their uppermostselective position. As trip-off lever 531 continues to be carriedrightwardly by bar 413, its laterally extending arm engages pin 538 andthe trip-off lever is rocked counterclockwise, as viewed in Fig. 1. Thecounterclockwise rocking of trip-off lever 531 causes it to be withdrawnfrom engagement with the lower end of latch restoring bail arm 532, andspring 533 restores bail 53| to extreme clockwise position, as viewed inFig. 3, in engagement with stop 534. Upon retraction of bar 413 tonormal position, the tripoif lever 531, after being withdrawn fromengagement with bail arm 532, returns to extreme clockwise position, asviewed in Fig.'5, in readiness to rock unlatching bail 531 upon the nextoperation of reciprocable bar 413.

As shown in Figs. 4 and 7, each of the bars 449 and arranged to blocksimultaneously or to un-v block a corresponding one of the transfer bellcranks 501 in each set 501, 502, or 503. Thus,

the uppermost of the bars 449 has projections 541 which will block thefirst transfer bell crank in each group, counting from the left, asviewed in Fig. 4, and these lugs will be moved out of blocking relationto the particular bell cranks 501 when the uppermost bar 449 is moved toits other selective position. Similarly, the bar 449 next below the tophas three lugs 541 which will block the second transfer bell crank 501in each group counting from the left when the bar is in one selectiveposition and which will not be in the path of those bell cranks when thebar is moved to its other selective position. Fig. '1 shows in detailthe relation of the lugs 541 to one set of transfer bell cranks 501. Itshould be noted that none of the lugs 54| carried by the bars 449 canblock one transfer bell crank 501 when in one selective position andanother of the bell cranks when in another selective position. Themovement of bars 449 from one to another of their selective positions issufcient only to move its lugs into or out of locking relation withrespect to particular transfer bell cranks.

It will be apparent that when latches 5.21 are withdrawn to theirextreme counterclockwise positions, as viewed in Fig. 3, and all of thestorage bars 501, 502, and 503 are permitted to rest upon the fixed stop526, the transfer bell cranks A501 associated with those of the bars501, 502, and 503 that had been previously elevated will be rocked incounterclockwise direction. Stop 526 is so positioned that the upwardlyextending arms of transfer bell cranks 501' cannot thereby rock intoengagement with the lugs 541 carried by bars 449, and thus there will beno interference with the setting of these bars by the three-armedintermediate levers 443. As the reciprocable bar 413 moves to itsextreme rightward position (Fig. 3), it rocks transfer bail 509 toextreme counterclockwise position, thus carrying the five transfer bellcranks 501 supported thereby to the left. Those of the transfer bellcranks 501 carried by bail 509 that do not encounter lugs 541 are merelymoved leftwardly idly, their horizontally extending arms moving betweenthe pins 504 and 506V of storage bars 50| without in any way affectingthe storage bars. However, those that encounter lugs 541 have theirupwardly extending arms arrested by the lugs and as bail 509 continuesto rock in counterclockwise direction, the blocked transfer levers 501are rocked in clockwise direction to lift their associated storage bars-501 against the tendencies of their individual springs. The bars thatare lifted, clear their latches 521 which respond to their springs 529and move into position to support the lifted storage bars. In

this manner, the storage bars 501 are set in positions corresponding tothe selective positions of the bars 449. c

Storage bars 502 and 503 may be set accordin to the next two signalcombinations in the same manner, the setting of the bars beingaccomplished by reciprocable bars 414 and 416 under the control of cams468 and 469. In this manner, there may be stored in the storage bars50|, 502, and I5133, code combinations representing three successivelyreceived letter codes.

The sets of storage code bars 501, 502, and 503 control the selection ofany one of a plurality of selectable slide bars 551 in a manner similarto va selecting system disclosed in copending application Serial No.333,161, filed January 17, 1929, by L. M. Potts. Referring nowparticularly to Fig. 3, it will be observed that the bar 5B1 seen inelevation is provided with a uniform distribution of notches and lugs.The space occupied by one lug and an adjacent notch corresponds to thatrequired by any one oit the plurality of tapes upon which printing is tobe effected. In this space is accommodated one of the selectable slidebars 551, there being one such bar for each tape upon which charactersare to be printed. `All of the bars Eiii, V592, and 553 are identicalwith the bar 50! shown in elevation in Fig. 3 in that they are providedwith a uniform distribution of notches and lugs. Thus7 there is nopermutational or other coding inherent in the notchings of the severalbars 551, 552, and 553. Slide bars 55| are shown in their extremeright-hand position in Fig. 4, and these bars are slidable leftwardlyunder circumstances about to be described, the leftward movement beingimparted by tension springs 552 individual to each bar 551. `rEach ofthe bars 555 is provided with three sets of notches, each set consistingof iive notches. The slide bars 55! are so positioned with reference tostorage bars 5M, 552, and 553 that the front edges of the storage barsare disposed in the notches in bars y554, the front edges of the storagebars being the edges provided with the uniform distribution or notchesand lugs, There are thus provided upon bars 555i a plurality of lugs orears 553. With reference to any of the storage bars 55, 552, and thelugs 553 disposed at the right of individual storage bars, as viewed iin Fig. a, are the ones which may prevent leftward movement of a slidebar 551.

As shown .in Fig. 3, the lugs 555 of slide bars 55! are bent upwardly ordownwardly according to a permutation code system whereby a bar Sill,552 or 553 may have certain of its lugs interposed in the path of lugs553 oi certain of the slide bars 55! when the storage bar is in itsupper selective position and may have others of its lugs interposed inthe path of lugs 553 carried by the remainder of the slide bars 558 whenthe storage bar is in its lower selective position. From this, it willbe apparent that for a given permutational setting of the storage bars555, 552, and 553 in upper and lower selective positions one, andaccording to the preferred embodiment of the invention only one, of theslide bars 55! will have all of its lugs in alignment with notches inthe storage bars whereby the slide bar will have been selected and willbe free to move leftwardly, as viewed in Fig. 4. With a diierentpermutational setting of the storage bars 513i, 55E, and 5135, anotherone or none of the slide bars 55! may be selected for leftward movement.

lAs is well known in printing telegraph systems operable in accordancewith permutation codes, five selecting bars will afford thirty-twousable selective possibilities. This is true of any oi the sets of vestorage bars 555i, 552, and 553. With three such sets jointlycontrolling the slide bars 551, the number or selective possibilities isvery much higher than can possibly be employed in a single printer.rThis arrangement will permit the coding of the slide bars 555 accordingto the actual letters of the stock designation. Thus, the 'oars 55S maybe set according to the code combination for the rst letter or" thestock, bars 552 may be set in accordance with the code combination forthe second letter of the stock, and

bars 553 may be set according to the combination` of the third letter ofthe stock designation. Some stock designations are customarilyrepresented by two letters and some by a single letter. For quotationsrelating to such stocks, it will be necessary to set permutationallyonly the storage bars 55! and 552 or only the storage bars 553i. Sinceprior to the setting of the bars 551 all of the latches 527 areretracted to permit all of the storage bars to .return to theirlowerrnost positions, those quotations which contain no second, orsecond and third letters will not involve permutational settings of thestorage bars 552 or 552 and and those bars will remain in theirlowermost positions. For such stocks, the slide bars will necessarily becoded to be selectable when the storage bars 552 and 553 are in theirlowermost positions and such slide bars will be blocked when a storagebar from a set for which the stock designation has no identifying letteris raised to the upper selected position. For settings or" the storagebars corresponding to designations of stocks other than those for whichtapes have been provided in a particular printer, no slide bar 555 willbe coded to be selected, and as the printing of a stock price occursonly as a. consequence of selection of a slide bar 551, the unwantedquotation will be rejected, as will presently appear.

At the left of each of the slide bars 55l, as viewed in Fig. e, is acombination print hammer and tape feeding control slide 555 and apivoted latch 557. Each print hammer slide 556 is provided with a notch558 to be engaged by the latch 55's'. Frint hammer slides 555 are urgedleftwardly by springs 55S and are restored to their extreme right-handposition by a bail 55! which is engageable with a hooked arm 552 carriedby each of the slides 555, and is biased to seek-engagement with thehooked arms 552 by a spring 555 which is very light as compared with thesprings 55S.

As may be observed by reference to Figs. 1 to 4, inclusive, bail 55!extends transversely of all of the print hammer slide restoring arms 552and is pivoted at 553. Clockwise rocking movement is imparted to bail55! to effect the restoration of slides 555 to their eXtreme right-handpositions, as viewed in Fig. 4, by a bail 555 pivoted at 565 andconnected to bail 555 by means of a link 55?, the connection betweenbail 55l and link 557 being a pin 558 and slot 559, as shown in Figs. 1and 4. Counterclockwise movement is imparted to bail 55| by theindividual print hammer slides 55.5 which are moved leftwardly by theirsprings 559.

The lowermost end of bail 555 is disposed adjacent to the right-handedge of the uppermost reciprocable bar dit and the bail is provided witha roller 5l! the horizontal plane of the reciprocable bar 553. As shownin Fig. 6, bar 413 has a portion at its lett-hand end of greater widththan the main body portion of the bar, and when the bar is in its normalor unoperated position, roller 555 engages the edge of bar 475 in themain body or narrow portion thereof. When bar 413 is moved rightwardly,as viewed in Fig. 3, in the manner previously described, roller 57irides up the slope between the narrow and the wide portions of bar 555whereby clockwise movement is imparted to bail 555 and through link 561to 552, by engagement of the left-hand end of slot 555 with pin 558.This movement of bail 55S by means of said bar 73 thereupon causesmovement of any hammer interponent assembly 556 which had been released,restoring it to its la-tched position as shown in Fig. 4:

Adjacent to the portion of bail 56| which engages print hammer sliderestoring arms 562, the lower arm of the bail pivotally engages a link512 which has intermediate its ends a notch 513. A latch 514 pivoted at468 and biased in clockwise direction by a tensionspring 515 entersnotch 513 in link512 when bail 56| has been rocked to extreme clockwiseposition and retains the bail in that position. The slides 556 are heldin their extreme right-hand positions, as viewed in Fig. 4, by theirlatches 551 and by the latched bail 56|. Tension springs 552 urge slidebars 55| into engagement with their associated slides 556 so that when apreviously selected slide 556 is restored to its eXtreme right-handposition, its associated slide bar 55| will also be restored to extremeright-hand position. As reciprocable bar 413 returns to its normalposition, bail 564 is moved by its restoration spring 565 to its extremecounterclockwise position with its roller 51| engaging the narrowportion, the pin and slot connection between link 561 and bail 56|permitting this independent movement.

The release of bail 56| to permit a selected one of the slide bars 55|to trip its associated latch 551 and thereby release its associatedprint hammer slide 556 for leftward movement, as viewed in Fig. 4, iscontrolled by the previously identified T-lever 452. Upon the receptionof a code combination which contains an impulse to controlrthe printingof figures, T-lever 452 is rocked counterclockwise, as viewed in Fig. 4,and

through pin 456 it rocks bell crank 458 clockwise.

Bell crank 458 has an arm 516, the free end of which is disposed in aslot in disc 511 which is sleeved on shaft 463 below ratchet 462. Disc511 supports upstanding pins 518, one of which is adjacent to pawl 459and the other of which is disposed adjacent to holding pawl V464 and toan arm of a bell crank 519 disposed above and extending parallel toholding pawl 464, the bell crank 519 and pawl 464 both being pivoted at469. When bell crank 458 is rocked clockwise by T-lever 452, disc 511 isrotated counterclockwise a suicient distance to cause pins 518 towithdraw operating pawl 459 and check pawl 464 from engagement withratchet 462. rocked counterclockwise through the same angular distanceas is pawl 464. Upon the release of the pawls 459 and 464, spring 466,Fig. 3, restores shaft 463 to normal position with the shoulder on stopdisc 41| engaging iixed stop 412.

` Bell crank 519 has an arm 58| which carries a pin 582 disposedadjacent to the end of latch 514 which holds bail 56 in eXtremeclockwise position. Pin 582v also engages one arm of a bell crank 583which is pivotally supported upon an arm |583 of shaft 6 |1 inassociation with a printing bail 584, the structure and operation ofwhich will be described later. The free end ofthe other arm of bellcrank 583 is provided with a latching shoulder which engages anextension 585 of the lever 45| which controls special blocking code disc441, and the latching shoulder normally holds the lever 45| in extremecounterclockwise position whereby disc 441 is normally presented in eX-treme clockwise position. Latching bell crank 583 is disengaged from theextension 585 of disc controlling lever 45| by pin 592 as bell crank 519is rocked counterclockwise, but lever 45| is not thereby released forthe reason that it is held by a second latch 586 pivoted at a, xed point581. At its foremosten'd, as Viewed in Fig. 4, latch 586 Bell crank 519is 12 carries a pin 588 which is disposed in a slot589 in the left-handend of link 512. Since link 512 is moved leftwardly with bail 56| whenthe latter is moved counterclockwise by a selected and released printhammer slide 556 upon the release ol latch 514 it moves idly withrespect to pin 588 carried by latch 586 until the right-hand end of slot589 engages the pin 588. Further leftward movement of link 512 causeslatch 586 to be with-'- drawn from engagement with lever 45| which,being biased in clockwise direction by a spring 59|, rotates itsassociated discv441 in counterclockwise direction.

Disc 441 is provided with notches spaced according to the spacing ofselectable pins 592 of code disc selector mechanism 448 (Fig. V 4). Whendisc 441 is in extreme clockwise position it blocks all of the pins 592and prevents any one which may otherwise have been selected bycode discs446 from moving inwardly radially of code disc selector mechanism 448.When disc 441 is rocked to extreme counterclockwise position uponrelease of latches 583 and 586, it presents its notches to all of theselectable pins 592 and any such pin to which an alignment of notches ispresented by the five code discs 446 is permitted to move inwardlyradially of selector mechanism 448.

The two latches 583 and 586 are provided because the control of blockingdisc 441 involves several factors. Latch 583 is released upon thetransfer of a signal combination in which the sixth pulse is of markingnature. Due to the association of latch 583 with the printing bail, thelatch is reengaged with and relatches the lever which controls disc 441after each printing operation, the purpose of this being to prevent asecond printing of a character in response to one selection of thatcharacter. Latch 586 is released by the latch link 512 of bail 56| atthe time that bail is moved into its extreme counterclockwise positionby a selected print hammer slide 556, the slide having moved intoeffective position at that time. It thus delays the unblocking of theprint-- ing control pins 592 to insure the operation of the print hammerslide. The latch 586 remains released until the selected slide 556 isretracted to ineffective position. The restoration of any one of saidslides 556 is eiected through the operationy of bail 56| as has alreadybeen stated. A

The movement of bail 56| in a clockwisedi` rection about its pivot 563is preceded by the operation of printing bail 584 which member, ineffecting printing, rotates clockwise about its shaft 6|1 until bailblade 626 is brought sharply against the interponent hammer 594 of theparticularly selected slide 556, whereby printing is effected throughpercussion engagement with an associated type Wheel 599. Upon therestoraftion of printing bail 584, however, which result is roller 628,shaft 6 |1 and all of its integrally associated elements is rockedcounterclockwise, and

as an incident thereto aforementioned arm |583,

' Fig. 1, which carries a latching-bell crank 583 and which had beenretracted during the printing motion of bail 584 is now rockedcounterclockwise as bail 584 is retracted so that the shoulder of bellcrank 583 may again engage portion 585 of blocking disc operating arm45| and rock the latter in a counterclockwise direction about itsshaft444 returning the selector block` ing disc 441 to its effectiveposition as indicated ini Fig. 4.

Latch 586 is also effective to prevent) Y. the operation of the printingbail 584 when stock price signal combinations are received for stocksfor which no coded slide bars or recording tapes have been provided.There will be no print hammer slide selected or released when theidentifying letter signals for such stocks are received, and thereforebail 5e! will not be rocked counterclock- Wise nor latch {i be trippedwhen the figure signals are received. Blocking disc filii will thereforebe retained in blocln'ng relation to pins 5e?, one of which must beselected in order to cause operation of the printing bail. Preferablylatch 583 holds extension 585 of lever 45| slightly iarthercounterclockwise than does latch 586, as the latter is required toengage and hold the extension, after the release of latch in suchposition that should latch 583 return to normal position before therelease of latch 586, the latch 583 cannot relatch the extension norotherwise deprive latch 536 of its proper control over blocking disc4117. f

Each of the print hammer slides 55E carries a flexible arm 593 at theleft-hand end of which (Fig. 4) is a print hammer head 5%. Intermediatethe ends of each slide 555 a spacing control pin 59B is reciprocablysupported, the pin being maintained in retracted position by acompression spring 597 which is compressed between one of the supportsfor pin 5% and a flange 5&8 carried by the pin. The movement of printhammer slide 55S leitwardly, as viewed in Fig. 4, when permitted by therelease of bail 56| and by the release of the latch 557 under thecontrol of a selected slide bar 55|, is suicient to bring the printhammer head Eet into printing position between the type wheel 599 andprint hammer operating blade 526 of print bail 58d, and to bring thespacing control pin 555 into alignment with the operating lug 613| of aspacing paw] 82. The apparatus is now in readiness for the printing ofthe gures of a stock quotation, the stock designating letters havingserved to elifect the selection of a particular print hammer slide 55Sand during the reception of the letters code combinations, the code discselector pins 592 having been blocked and prevented from responding tothe letters selections by means of the special blocking disc 447.

The type wheels 599 are secured to type wheel shaft m5, which iscontinuously rotatable. Ad-

jacent to the top of code disc selector mechanism 448, type wheel shaftcarries in fixed angular relation to the type wheel an arm 6%3 (Figs. 3and 9) At its outer end arm 653 pivotally supports a print bailcontrolling lever 5534. Lever E54 is provided at its outer end with anobliquely directed extension 5&7 which trails the lever Eil as arm Srotates. Extension 5137 of lever 594 revolves about the axis of shaftetti just inside the alignment of selectable pins 592 when those pinsare in their outermost or unselected positions. When all of theselectable pins 592 are blocked by the special disc l, arm GES and lever664 revolve idly as shaft et rotates and the trailing extension 697 oilever does not come into engagement with any of the pins 592. However,upon the selection of one of the pins 592, its upper end is moved intothe path of obliduely disposed extension 5&7 of lever 504 and when thetrailing extension comes into engagement with the selected pin, it ridesover the top of the pin, 7

thus rocking lever Et countercloclcwise, as viewed in Fig. 3, andthereafter drops oi, permitting the lever to return to normal position.

Above the code disc selector mechanism 48, shaft e8 carries a sleeve 638which is urged upwardly by a compression spring 609. Sleeve 8 isprovided with spaced anges 5| l. The inner end of lever 64 is disposedbetween two of the flanges 5H so that when lever tell is rockedcounterclockwise (as viewed in Fig. 9) by one of the selectable pins5&2, sleeve 663 is moved downwardly along shaft lille, therebycompressing spring tl. The free end of a latch 6i? pivoted at 613 isdisposed between two of the discs 6| so that when sleeve lit is moveddownwardly, latch BlZ will be rocked clockwise, as viewed in Fig. 3.

Latch is provided with a vshoulder which normally holds printing bailarm i585 in the position shown in Figs. 4- and 5, the bail being biasedin clockwise direction against the shoulder by a tension spring ti@(Fie. 5) connected to an arm 5| E secured to the shaft 6 i 7 to whichprinting bail 584i is secured. Arm Sie is disposed in the samehorizontal plane as a bail restoring cam l l 8 which is carried by mainshaft dil@ and is connected to the shaft through a friction clutch.Above the cam il and connected thereto for controlling the rotation is astop disc tlg which is provided with stop shoulders equal in number andspacing to the number of bail restoring apices with which cam 558 isprovided. A sto-p pawl 62| is pivoted at 622 in the same horizontalplane as stop disc 659 and is urged by tension spring 623 intoengagement with the stop disc. At the opposite end from that whichengages stop disc 5|9, stop lever $24 is provided with a depending pini524 which is disposed in the path of printing bail arm 'l when thelatter is rocked in clockwise direction.

Upon the release of latch Sill, printing bail 584 is rocked. inclockwise direction by spring 554 to cause blade 26 carried by bail 584to strike a selected print hammer head 55d to cause it t0 strike againsttype wheel a tape upon which printing is to be effected and an inkribbon being interposed between print hammer head E94 and type wheel aswill appear hereinafter.

As the printing stroke is performed, a roller carried by the free end ofbail restoring arm tit is brought into engagement, with restoring camM8. Restoring arm Ei' in moving to its eX- treme clockwise positionrocks stop lever 52| counterclockwise, as viewed in Fig. 4:, due toengagement with its depending pin Sie. Stop lever 62%y is thus withdrawnfrom engagement with a shoulder of stop disc SEQ and rotation isimparted to cam tit and disc ifl by shaft 38. The rotation of shaft 1298is in clockwise direction, as viewed in Fig. 5, and cam |558 rocks leverarm 6l 5 and therefore bail 535i counterclockwise a distance greaterthan that required to re-engage it with latch e l L. the overtravel incounterclockwise direction being provided for the control of tapespacing as will presently be described. As bail restoring arm Elli isrocked c-ounterclocliwise, it is withdrawn from engagement withdepending pin 52:3 of stop lever 2i which is thus enabled to return toengagement with Stop disc Elli to arrest the disc by engagement with thenext succeeding shoulder carried thereby. Cam dit and disc i are notarrested until after a restoring apex cam B! 8 has passed and moved freeof roller 529 whereby arm il returns in clockwise direction from itslimit of overtravel until bail l engages the shouldf on latch The bailEte is thus prepared for the next release of latch El? when it can herocker.' in clockwise direction by spring tid, printing thus being 'oyspring and restoration by cam, from which roller i523 is held disengagedin normal or idle condition.

As previously stated, each of the type wheels carried by shaft 466 hasassociated with it a tape upon which quotations are to be printed.` Thetapes, identied by reference numeral 636, are supplied from individualtape rolls 63|, each of which is supported, as shown in Fig. 10, on anindividual arm 635 pivotally supported on a vertically disposed post646. Adjacent arms 635 on post 640 extend on opposite sides of a limitbar 645 against which they are biased by individual springs 656, theleitwardly extending arms in counterclockwise direction and therightwardly extending arms in clockwise direction. Tape guides 655 maybe provided for guiding the individual tapes from their respectivesupply reels to their tape feed control rollers 632 with which the tapesare frietionally engaged by pressure rollers 633.

With the arrangement described in the foregoing paragraph two verticalalignments of tape supply rolls are provided, a space intervening anytwo adjacent supply rolls on one side of limit bar 645, due to thealternate disposition of successive supply rolls on opposite sides ofbar 645. The space provided aords access to individual supply rollsupports, and an exhausted supply of tape may be replenished by swingingthe particular arm 635 away from limit bar 645 and clear of the othersupply rolls on the 'same side of bar 645. Thus, the supply rolls areindividually and independently supported, and may be replaced withoutdisturbing any other supply rolls.

The tape feed controlling rollers 632 are mounted one above the other ona stationary shaft 636 and are individually rotatable upon the shaft.Each feed roller 632 has secured thereto a ratchet wheel 531 which isengaged by the previously identified escapement Vpawl 662. Each of thepawls 602 is biased to extreme counterclockwise position by a spring638. As shown in Figs. 1, 2, and l0, shaft 6I1 to which printing bail584is secured also has xed thereto a spacing bail 636. lThe free end ofbail 639 is in alignment with the operating lug 66| carried byescapement pawl 662, and when print hammer slide 556 is moved to theleft, as viewed in Figs. l and 4, the reciprocable pin 596 becomesaligned with lug 66| and with 'spacing bail 639. Upon the release ofprinting bail 584 by latch BIZ (Fig. 5) and during the movement ofprinting blade 626 through its printing stroke, spacing bail 639 isdrawn away from the end of pin 596. Reciprocation of pin 596 to eiectclockwise movement .of escapement pawl 662 is accomplished during thatportion of the counterclockwise movement of bail arm 6 I 6 which waspreviously identified as overtravel beyond the position for latching ofbail 584. When pawl 662 is rocked, ratchet wheel 631 escapes forrotation through a distance equal to one character space Y and the tape,which is pressed against roller 632 by pressure roller 633, is advancedby the tape puller drum. Before cam 6|8 is arrested, follower roller 620drops oi the apex of cam 618, as previously described, and spring 6|4withdraws bail 639 from engagement with pin 596, thereby permittingspring 591 to retract the pin to normal position and spring 638 torestore pawl 602 to its normal or extreme counterclockwise position.

The spacing mechanism provided in the printer herein described includesmechanism for automatically inserting a space between any twoconsecutive quotations on a tape. Thus, no tape spacing signal need betransmitted to eect separation of the quotations. This mechanism isshown in Fig. 4 and comprises a cam projection `625 on print hammerslide 556 which engages operating lug 60| of spacing pawl 662 and holdsthe pawl in clockwise position when slide 556 is latched in itsright-hand position, thepawl being released and permitted to rock tocounterclockwise position when slide 556 moves to the left. Aspreviously described, one cycle of oscillation of pawl 662 results inthe advancement of tape 630 one character space. print hammer slidefollowing the printing of a stock price, and the release of theslidepreparatory to the printing of another quotation relating to thesame stock, the pawl 662 is oscillated through one complete cycle, andtherefore the tape will be advanced one character space, the advancementbeing accomplished in two steps. The first step, representing part ofone tooth distance on the ratchet wheel 631, occurs following theprinting of a-stock price, and the second step, representing theremainder Vof onetooth distance, occurs before the printing of the nextquotation on the same tape. During the printing of a quotation, camprojection 625 isclear of pawl 662, so that it does not interfere withthe operation of the pawl by pin 596.

A simple modication of cam projection 625 willv permit the apparatus tointerpose two chai'- acter spaces between any two quotations on a tape.This `may be accomplished by providingV a cam slope on the left-handedge as well as on the right-hand edge of cam projection 625, and byrelocating it so that it is at the right of pawl projection 66| whenslide. 556 is at extreme right, and is at the left when slide 556 is atextreme left. With this arrangement, cam projection 625 operates andreleases pawl 662 upon being re.- tracted, whereby the tape 630 iscaused by roller 632 to advance one character step, and Valso operatesand releases pawl 602 upon movement to effective position preparatory toprinting, whereby the tape is advanced another character step.

The tape puller drums 64I are rotatably4 mounted upon hub sleeves 642carried by shaft 643. Continuous rotation is imparted to shaft 643 fromtype wheel shaft 466 through gear 656 carried by type wheel shaft 466(Fig. 3), gears |655 and 658 carried by an intermediate shaft 651, andgear 659 carried by shaft 643 (Fig. 1). 64I is capable of rotationwithrespect to hub sleeve 642 and the drum and sleeve -are both normallystationary while shaft 643 by which they are supported rotatescontinuously. One end of a flat coiled spring 644 is' secured to theinner annular surface of drum 64I, and the other end is secured to hubsleeve 642. The Vhub sleeve 642 has secured thereto a check ratchetwheel 646 which is checked against counterclcckwise rotation by springbiased check pawl 641. Hub sleeve 642 also has secured thereto a disc648 on which is pivotally mounted a spring winding pawl 649 engagementwith drum 64| by pressure roller 654,Y

carried by spring biased pressure roller arm 656. As drum 64| rotatesclockwise in advancing the tape, it advances its pin 652 until the pinis moved Y out of engagement with the tail cam of pawl 649,

which is-thus urged by its spring 65| into eni gagement withcontinuously drivenratchet 653.

By the retraction of the Drum Rotation is thus imparted from ratchet 653through pawl SL39, disc E48, and hub sleeve 642 to rewind spring E44.During this rewinding, check ratchet B46 advances tooth-by-tooth withrespect to check pawl B41 and holds hub sleeve 52 against reverserotation upon the disengagement of pawl 55S from ratchet E53. Therewinding of spring 644 is terminated when the tail cam of pawl S49overtakes and engages drum pin 552. The pin engages the cam andwithdraws pawl 649 from engagement with ratchet 653, whereupon theclockwise rotation of hub sleeve M2 is arrested. The head of pawl 649 isprovided with a iinger 651, the end of which is disposed in closeproximity to the inner annular surface of drum 64| when pawl 6!! is heldout of engagement with ratchet 553 by pin 652. Finger 657 blocks thepath of pin 652 whether pawl 54S is engaged with or disengaged fromratchet 653 and assures engagement of the pawl with the ratchet as wellas prevents unwinding of spring tilt by limiting the amount of clockwiserotation of drum 54S relative to hub sleeve B42.

Since the driving torque is applied to drum 64I solely through spring'l-i4, it will be apparent that there is no restraint uponcounterclockwise rotation of the drum and, therefore, that the tape maybe retracted, if desired, without necessitating slipping of the tapewith respect to drum 6ft i. Use is made of this feature of the presentinvention by providing means for effecting a retraction of the tapeprior to the printing of a stock quotation and permitting the tape toadvance the distance that it was retracted, following the printing ofthe quotation. The necessary concentration of certain elements at theprinting point, such as, the printing bail, ink rib-bon, and type wheel,may cause the last character or last few characters to be obscured byelements of the printer and to become visible only after the tape hasbeen advanced several character spaces. When the printed characters areto be projected upon a viewing screen, a greater number of the mostrecently printed characters on the tape may be outside he eld of theoptical system, due to the presence of structural elements of theprinter at the printing point. The advancement of the tape a sufcientdistance to bring the last character printed into position to beobserved directly may not be suflcient to bring it into the field of theprojecting system. Merely to advance the tape several character spacesfollowing the printing of each quotation has certain disadvantages amongwhich is the relatively wide blank space that appears between quotationson the tape with the result that only a small number of quotations mayoccupy positions in the projecting held at one time, the wide spacesbetween quotations on a tape being entirely wasted. To overcome thesedisadvantages, the present invention has been provided with means forfor-ming a loop in the tape between the supply roll and the printingposition prior to the printing of a quotation, the loop being formed bymoving the tape backward against the torque supplied by spring tali tothe tape feed drum SM, the tape between the point of formation of theloop and the supply roll being held stationary by the tape feedcontrolling roller 632.

Referring particularly to Fig. 4, it will be observed that print hammerslide '556 has been provided with a leftwardly extending arm 65| at thefree end of which is a roller 662. The length of arm i is such that whenthe slides 55B are held in their eXtreme right-hand positions, as

' roller 34.

viewed in Fig. 4, the tape will be permitted to occupy an approximatelystraight path between tape feeding control rollers 632 and idler rollersS34. However, when a print ham-mer slide 56 is released for leftwardmovement by the tripping of its latch Effi by a selected slide bar 5.5i,the roller 52 will be moved leftwardly and will increase the length ofthe path between the point of engagement of the tape with rollers 632and $33 and the point of its engagement with idler The tape required toincrease the length of the path will be supplied by rightward movementof the tape past the printing position, as viewed in Fig. 4, tape feeddrum @Iii rotating counterclockwise as the tape is retracted. Thus, themost recently printed quotation on the tape will be moved back towardthe printing position, thereby reducing to a predetermined low amountthe blank tape intervening adjacent quotations. Printing of the figuresof the'quotation may then proceed in the normal manner, the tape beingadvanced one character space for each character printed, by the tapefeed controlling roller E532. After the last character of the quotationhas been printed, and upon the next clockwisey movement of bail 236i toits latched position, the print hammer slide '556, which has beenselected, will be restored to its eXtreme right-hand position and rollerS62 will be retracted to permit the tape to assume an approximatelystraight path between rollers 532 and 6316. The reduction in the lengthof the path between these two points will result in slack tape whichwill be taken up by tape feed drum 54H, thus advancing the lastquotation printed from the printing position by the distance that thepath is reduced. In order that the retraction of the tape, which causescounterclockwise rotation of drum Gill, shall not draw pin 652 olf thecounterclockwise end of the tail cam of pawl whereby the pawl wouldescape from control by the pin, the tail cam should be of sufficientlength to accommodate retraction of the type while maintaining pawl tfidisengaged from ratchet 653.

An ink ribbon supporting and feeding mechanism is provided for passingan ink ribbon, such as is used on typewriters and various forms ofprinting telegraph apparatus, between the tapes 639 and the print hammerheads 5% when the latter are moved into printing position. The ribbonspool supporting and driving mechanism is similar to that shown incopcnding application Serial No. 77,796, filed May 4, 1936, by AlbertH.'

Reiber. As shown in Figs. l, 2, and 4, a ribbon feed mechanismsupporting plate 565 is mounted above the primary selector mechanism andis provided with spindles 667 upon which ribbon spools 668 are adaptedto be mounted. Each of the spindles SS has secured thereto a ribbon feedratchet 66S, as shown in Fig. 2. A ratchet feed pawl (not shown) isprovided in accordance with the disclosure of copending applicationSerial No. 77,796 for imparting rotation alternatively to either of thespools 5&3 and, in the present adaptation of the apparatus, the pawl isoperated by a link 61| which is pivoted to a lever arm 672 secured toshaft 6H which carries printing bail 584 and tape spacing bail 639. Uponeach operation of printing bail 584, clockwise rotation is imparted toshaft SVI by the printing spring Gili and counterclockwise rotation isthen imparted to the shaft by restoring cam SIB. Link 57i is then movedendwise and is retracted to effect rotation of whichever of the ratchets665 the ribbon feeding pawl engages.

From the left-hand of the spools 668, ink ribbon 513 passes behind theribbon guide 614, and around the obliquely cut right-hand end of theguide E574, whereby the path of the ribbon is changed from horizontal tovertical. The ribbon extends upwardly past all of the tapes 53) andacross a, horizontally disposed guide mounted above the uppermost of thetype wheels by which the ribbon is directed rearwardly of the printer.From this point, the ribbon extends downwardly behind all of the typewheels to a point below the lowermost of the type wheels where there islocated a guide similar to the guide 614 for changing the direction oftravel of the ribbon from vertical to horizontal. The ribbon is thenbrought forwardly to the right of the printing position, being guided bymeans of pins E15, and is engaged with the right-hand spool 558. Byvirtue of the provision of two ratchets 565, the direction of travel ofthe tape may be reversed. Thus, at times the ribbon 6'13 may passupwardly in front of the tapes and at other times may pass downwardly,being alternately transferred from the right-hand to the left-hand spooland from the left-hand to the right-hand spool.

The multiple tape printer, hereinbefore described, is shown in allfigures in the normal or idle condition with the single exception ofprint hammer slide restoring bail 55|. IThis bail is not restored toeXtreme clockwise position as an incident to the printing of a stockquotation, but remains in its extreme counterclockwise position,permitting a selected print hammer slide 55E to remain in its extremeleft-hand position, as viewed in Fig. 4, until the reception of the neXtsignal combination transmitted, which would ordinarily be the signalcombination relating to the rst stock designating letters of the nextstock quotation.

Upon the reception of the first code combination representing adesignating letter of the stock for which a quotation is to be printed,the sword levers El are set according to the code combination, thetransfer levers are unlocked and are set in correspondence with thereceived code combination by the transfer bail, which also rocks theT-lever 452 in clockwise direction, due to the fact that the codecombination represents a letter and the impulse which distinguishesbetween letters and figures is of spacing condition. The T-lever 452 isnot provided with a locking extension to be locked by the bail whichlocks transfer levers 426, for the reason that it performs thefunctions. for which it is provided merely by rocking to its clockwiseor counterclockwise position, and it is not necessary and may not bedesirable to lock it in those positions. The lT-lever operates pawllever 457 to effect the rotation of ratchet wheel 462 and shaft 463 onestep. The uppermost of the reciprocable bars 413 is thereby conditionedfor operation by bail 485.

In timed relation to the unlocking of transfer levers 425 and thesetting of discs 446 and bars 449, reciprocable bar M3 is operated toeffect the restoration of bail 56| to latched position, whereby thepreviously selected print hammer slide 556 and all of the other slides555 as well are retracted to eXtreme right-hand position, as viewed inFig. 4 thereby; to operate bail 53| to disengage all of the latches 521from the transfer bars 55| to permit those bars to drop to theirlowermost position; and to operate bail 492 to effect the setting ofstorage bars 55| in accordance with the setting of bars 449 through theagencyoftrans.-

fer bell cranks 5G? carried by bail 55S. During this time, all oftheselectable pins EQ2 are blocked from being selected by special blockingdisc 441 whichis latched in extreme clockwise position by latch 56,3,which is pivoted on an arm met carried by printing bail shaft l'l andwhich is, Y

therefore, operated to restore disc 44? to blocking relation toselectable pins 52 following each printing operation. llShus, none ofthe pins 592 can move into selected position during the reception ofstoel; designating letter combinations ond and third positions, wherebyfirst the bar.

ll'l'tl and then the bar file will be actuated by bail 486 to effect theoperation of bail i973 and 484 to store in bars 562 `and the successiveselective conditions of barsA 449.

If the stock designation should consist of only one letter or of twoletters, thebars 592 and 563, or the bars 5i3, respectively, will not beset but will remain in their lowermost positions, to which they wererestored by their springs upon the operation of bail 53| in connectionwith the 4transfer of the rst received code combination.

If any stock designation should contain more than three letters, or ifmessage material such as news bulletins should be received bytheselector, the letter codes in excess of three will have no effect on thesignal storage mechanism. They will merely attempt to step ratchet 462,and as the ratchet has four notches in addition to that which is engagedby pawl 459 in the rest position of the ratchet, as shown in Fig. 1, itcan be stepped only until cam 469 has been carried one step beyond itseffective position.

Following the last letter of the stock designation, whether thedesignation has consisted of one, two, or three letters, the signalcombination representing the first gure of the price quotation will bereceived. In this signal combination, the impulse which determines thatit pertains to a figure will be of marking nature, and the T-lever 452'will be rocked in counterclockwise direction. This determines that thelast of the letters of the stock designation has already been receivedand no idle interval, representing the time for setting the storage bars552 and 553, need be interposed between the last letter code of a stockdesignation consisting of less than three letters and the first figurecode of the price.

The counterclockwise rocking oi T-lever 52 causes pawls 459 and t to bestripped from engagement with ratchet 352 which permits shaft 4&3 toreturn to normal position. Bell crank 579 Y is rocked counterclociwiseas holding pawl 464` is disengaged from ratchet e232, the rocking ofbell crank 5N resulting in therelease of printing hammer slide restoringbail 55E andthe simultaneous release of one of the latches holding thespecial blocking disc 44? in blocking position withV respect toselectable pins 5d?. As bail 55| rocks to counterclockwise position, ittakes up the lost motion afforded by slot 558, and thus becomes closelycoupled to bail 55d for subsequent restoration to extreme clockwiseposition. Thus, one of the print hammer slides 555, corresponding to theslide bar 5.5i, which had been released as a result of the setting ofstorage bars 5m, 552, and 5%3 according toY the code combinations representing a stock combination, becomes unlatched and is moved by itsspring 559 to present its print hammer head 59o in printing position.This movement causes loop forming roller to2 to form a loop in the tapeupon which the quotation is to be printed, and the tape is therebyretracted to reduce the blank space between the last printed quotationand the printing position.

At the end of the counterclockwise travel of bail Sl, secondary latch585 for blocking disc 134? is released and this latch will remainreleased until bail 55! is restored to extreme clockwise position, whichoperation will occur in connection with the reception of the codecombination representing the first letter of the neXt stock quotation.Upon the release of disc @47 all of the selectable pins 592 areunblocked and the pin corresponding to the code combination of the firstfigure of the price moves into the path of printing control lever Stiland rocks that lever to efeot the release of printing bail latch H2,whereupon the bail blade 25 strikes the print hammer head 594 which ispresented in its path and causes the figure corresponding to theselected pin 592 to be impressed upon the tape by the continuouslyrotatable type Wheel. Upon the restoration of printing bail 53d tonormal position, spacing ratchet escapement S22 is operated to permitthe tape to be advanced one step and primary latch 533 for blocking disclil? is re-engaged with the disc controlling lever 45t is actuated torestore the disc to blocking relation to selectable pins 592.

The code combination representing the next figure in the price alsocontains a marking impulse indicating that the code combination pertainsto a figure, which again causes bell crank 458 to be rocked in clockwisedirection. Pawls 559 and iSd are again disengaged from ratchet 4t2. butsince this ratchet has already returned to normal position the operationis idle. Lever 57: is operated along with holding pay/l litt, as before,but this operation is not idle, the latch 58S being thereby againdisengaged from blocking disc controlling lever del. Latch 33 isreleased and disc Llll is rocked to its extreme counterclockwiseposition, thus permitting a selectable pin 5.512 to move into the pathof the type Wheel shaft arm, whereby the next figure of the stockquotation price is printed. The type wheels may be provided withfractions and any marks of punctuation and special characters ordinarilyused with or as part of stock quotation prices. During the printing ofthe several gures of the stock price, the code 'bars lfl are set inaccordance with the setting of the code discs Mt, but since ratchet @.52is not operated in response to signal combinations containing an impulsepertaining to the selection of gures, the transfer bails il, El, and 51dare not operated.

By means of the apparatus hereinbefore described, quotations fromselected stocks may be printed upon individual tapes identied with thestocks so that the stock designation letters are not printed but areused for selecting the tape kupon which the quotation is to be printed.A much larger number of quotations may thus be displayed or projectedthan there could be if the stock designation letters accompanied eachquotation on the tape. Furthermore, the latest quotation With referenceto any stock is moved out into position to be observed or projected assoon as a code combination in which the sixth pulse is of spacing naturehas been received, such a code combination causing the stock slide lastse- 22 lected to be retracted. When a price is to be printed upon anytape, the tape is retracted so that the quotation is printed inproximity to the next preceding quotation, thus further increasing thenumber of quotations that may be applied to a given length of tape.

The printer hereinbefore described if desired, be employed directly as aquotation board, by printing on relatively wide tapes with suioientlylarge characters to enable them to be read at distances from whichquotation boards may ordinarily be observed. This requires considerablylarger type Wheels than those employed in ordinary type Wheel telegraphprinters. 'The fact that the type Wheels of the printer according to thepresent invention are rotated continuously renders the printerparticularly adapted to the use of large type wheels because the inertiaeiects which would interfere with the arrestznent of all of the ypeWheels for each printing operation are avoided.

A modified form of tape retracting and releasing mechanism is shown inFig. le, other elements of the printer Which have already beenidentilied in the foregoing description being designated by the samereference numerals. In the modified form of tape controlling mechanism,print hammer slides 55% are not provided with tape loop forming rollersas in the previously described apparatus. Additional fixedly locatedidler rollers are provided, however, there being two designated by thereference numeral till to be engaged by the right-hand face of the tapeas it passes from the tape feed roller that face being the front of thetape, and two rollers 682 to be engaged by the sarna face of the tapejust in advance of the point of engagement of tape G30 with the tapepuller drum till.

A loop forming device vvhich comprises roller supporting platforms 5523and :i joined by a connecting bar which must be small as possible and asclose to the possible to avoid interference with a light beam when aprojecting system is used with the printer is supported for endwisemovement adjacent to each tape. Platform 533 supports loop formingrollers 687. The rollers 558i' are so positioned with respect to therollers ESS that ther,7 move through the plane dened by the rollers tillas platform @t3 is moved rightwardly. Similarly, platform Sll isprovided with rollers 33 so positioned With reference to rollers thatthey may move through the plane defined by the rolers 582 when platformis moved to the right. Rollers 68? and 538 engage the rear surface ofthe tape and the rollers S83 are disposed a substantial distance to theleft of the rollers tei?. so that the tape follows a tortuous rollers838 and S82 alternately to reach tape puller drum 613i. Thus, therollers form loops of substantial dimensions in the tape beyond theprinting point.

When the tape loop controlling device which comprises platforms 33 an Mand co @Gia gradually reduced in size until left- 684 engages stop TQ3.As rollers d are ca rightvvardly and the loops formed thereby arediminished, the rollers f' pass through the plane defined by the axes ofrollers and continue rightwardly thereof to forni loops in the tape atthe right-hand end of the tape loop controlling device. The transferenceof tape loops from the left-hand end to the right-hand end of the tape23 loop controlling device is accompanied by movement rightwardly pastthe printing position of a section of tape which had previously movedleftwardly past that position. Thus, the retraction of the tape topermit the printing of a stock quotation price in close proximity to thepreviously printed price which had been drawn out into viewing orprojecting position and the drawing out of the printed quotation intoprinting or viewing position following the printing operation resultssolely from the transference of slack accumulated in the form of loopsfrom one side of the printing position to the other Withoutnecessitating movement of the tape past the point of engagement withtape feed controlling roller or tape advancing drum Scl. Since fourpasses of tape form the loops around rollers G82 and i338, the tape loopforming device need be moved only one-fourth of the distance that tapeE335 is to be retracted or advanced by the transference of loops fromone side of the printing position to the other.

For moving the tape loop device to the right, as Viewed in Fig. 10, toretract the tape toward the printing position, there has been provided alever 69! pivcted at 5:3@2 and carrying a pin S93 which is disposed in aslot 6&6 in platform 5&3. Lever 59 is provided with a cam followerprojection Sgt* engageable with a cam 691 carried by a shaft ESS- anddriven therefrom through a friction clutch. A tension spring @SS biaseslever 691 in clockwise direction to maintain engagement of cam followerprojection Sgt with cam El. A stop disc it! is provided with shouldersengageacle with the armature 1&2 of an electromagnet '83 when the magnetis deenergized. The circuit of electromagnet 'i133 includes a pair ofcontacts 'ifl adapted to be closed by a lug 156 carried by print hammerslide 5555 when the print hammer slide moves to its eXtreme left-handposition. Upon energization, electrcmagnet 83 withdraws its armature 192from blocking engagement with stop disc lei, whereby cam 69? is releasedfor rotation and continues to rotate until the print hammer slide 555 isrestored to its extreme right-hand position which, as previouslydescribed, occurs upon reception of the first signal combination of, thenext stock quotation identification. As cam $9? rotates, it rocks leverSill to its eXtreme counterclockwise position in opposition to itsbiasing spring E9e. As lever Esi is rocked to that position, it takes upthe lost motion afforded by slot E915 and then moves the tape loopdevice to its extreme righthand position, slot 59d being wider at itsrighthand end than at its left-hand end to permit the tape loop deviceto move in a straight line while lever 6st moves in an arc. Stops 'miand lil are provided for limiting the movement of the tape loop devicein right-hand and left-hand direction respectively. It is important thatstop 'l shall be so positioned as to afford the tape loop device sucientmovement to the right to permit cam follower projection 556 of lever @Sito clear the cam projection of cam 6.9L

As cam follower projection 6% escapes from each of the projections ofcam 691, spring 599 attempts to restore lever Sill to its normalposition, However, the clockwise motion of lever till is retarded by adashpot device 108 which prevents lever @Si from rotating clockwise asufcient distance to take up the lost motion afforded by slot E94 duringthe rotation of cam E91 the distance of 180 between its campro-jection.Y Lever 139i may move a short distance in clockwisedirection between cam projections, but

it will be restored to extreme counterclockwise position immediately andthe result will be a slight oscillation of lever 69| which,v however,will not be imparted to the tape loop device which comprises platformsS33 and 684 connected by bar 688.

Fig. l1 shows in schematic form an arrangement for projecting realimages of the stock quotations printed on multiple tapes` upon a viewingscreen. The multiple tape printed is indicated merely by a diagrammaticshowing of a tape supply roll, a tape idler roller, a type wheel, andthe tape puller drum. At the rear of the printer are located a lamp 1il, which is backed by a reflector 'H2 for concentrating and focusing theillumina- 1 tion, and a condenser lens system lift. In front of theprinted tapes is located an objective lens 'l' I4 by which the beam oflight passing through the tape may be focused upon a plane reflector 'lHi. Plane reflector 'l I turns the beam of light through and directs itto the rear of a translucent viewing screen 'l l 'i from the frontofwhich the images of quotations printed on the tape of the printer maybe observed. The transmission of light through the tape from the rearand the use of a single objective lens and a plane reflectornecessitates the printing of figures upon the tape in the position shownin Fig 14, the tape being viewed from the front. With the charactersthus printed, the image inversion and rotation taking place at objectivelens lli and reector 'l l5 will produce upon viewing screen lll, whenviewed fromftlie front of thefscreen, erect real images of the printedcharacters moving from right to lett as the tape is advanced, which isthe actual direction of movement of the tape from the printing ingribbons and the print hammers are in front of the tapes, the characterswill be arranged on the type wheel according to the showing of Fig. 13.It is to be noted that printed characters viewed from the front of thetape, which is the side upon which they are printed, appear in the samerelative positions that they do on the type wheel. For this type ofimage projeotion,-it is desirable to use transparent tape for theprinting of the quotations in order that the translucent viewing screenshall be brightly illuminatedY to cause the dark type impressions tostand out distinctly.

It will be apparent from Fig. 11 that the pro-V` jectingsystemhereinbefore described is readily other and obliquely to the backwall, and a plui rality of viewing screens parallel to the wall.

In order to keep the projection distance a minimum and in order toemploy the most economical optical arrangement, the tapes are dividedinto groups and short focal-length, inexpensive condenser and projectinglenses are used with each group of tapes, in place of a lesser number Yof long-focus and much more expensive condenser and projecting lenses.The importance of keeping the projection distances low is to reduce f"the total spaceV occupied so that the Aboard can position. Since thetype Vwheels are located behind the tapes but the inkbe used Where spaceis very limited or is expensive. This arrangement is shown in Fig. 12,wherein a single type Wheel shaft lie and single set of each of thestorage bars iii, 552, and &33 serves to control the printing upon twoor more sets of tapes spaced according to the vertical dimensions of thetape images.

It should be noted that the optical system of each group of tapesinverts, in the image, the order of the tapes in that group, causing theuppermost tape of a group to appear at the bottom of the image of thegroup upon the screen. Such inversion of individual groups causes te bebrought into adjacency on the screen the uppermost tape oi one group andthe lowermost tape of the group next below it. This necessitates that ifthe tape images are to appear on the screen in a particular order, adiiierent order of coding the print hammer selecting slides, havingreference to the group inversion, must be established in the printer.Thus, if an alphabetical order of tape images is desired, the order oftapes in the printer must be from bottom to top of the uppermost group,then from bottom to top of the second group, then from bottom to top oithe third group, and similarly down to and including the lowermost groupof tapes.
